摘要: Abstract A new sol–gel route using egg-white as the binder of metal ions, is developed to prepare hexagonal M-type SrFe 12 O 19 ferrite in this study, and effects different atomic ratio Sr Fe (Sr/Fe), sintering temperature ( T s ) usage M ew on phase formation, morphology magnetic properties specimens are studied. It found that single-phase only can be obtained under a Sr/Fe 1:8 between 1000 °C 1300 °C. The also obviously affected by , primarily due emergency impurities. has an obvious impact crystallinity specimens, which consequently affects their properties. In our optimum conditions Sr/Fe=1:8, = 3 g =1200 °C.
